Follow the day-to-day drama of this volatile father and son team as they battle impossible deadlines and each other to push the envelope of motorcycle design and fabrication.
Over the past year, Paul Sr. and Paul Jr. have taken steps toward mending their once fractured relationship. Faced with the challenges of a changing market and a need to build mind-blowing bikes, the Teutuls must push their limits on every signature build. Paul Sr. takes a risk at Orange County Choppers as he moves his bike designs in a different direction.

Still, though their lives have evolved, the guys' commitment to building the most incredible bikes in existence has never faded - Paul Sr. and Paul Jr. even take steps towards mending their relationship, working together for the first time in 10 years.
